The tube and the product are part of a holistic design whole.
Pringles are made by pressing ground up potato paste into a disc shape and drying them. That makes them weaker than regular potato chips, necessitating a rigid tube container.
You might ask why make chips that way in the first place? My hunch is that they exist as a way to use up byproducts produced by other potato products. Sort of like how sawdust from lumber production is used to make particleboard.

Pringles are essentially edible particleboard.
